以紫薯为原料,进行酶解处理,再利用液态深层发酵的方法生产紫薯醋,研究了紫薯醋酿造的最佳发酵工艺,结果显示,在温度30℃下,酒精发酵最佳条件为:初始pH5、初始糖度14%、酵母添加量0.2 g/(100 ml);醋酸发酵最佳条件为:初始酒精度为6%、菌种添加量18%、装瓶量50%,对以薯类等淀粉基原料进行醋的工业化生产具有一定指导意义。
以紫藷為原料,進行酶解處理,再利用液態深層髮酵的方法生產紫藷醋,研究瞭紫藷醋釀造的最佳髮酵工藝,結果顯示,在溫度30℃下,酒精髮酵最佳條件為:初始pH5、初始糖度14%、酵母添加量0.2 g/(100 ml);醋痠髮酵最佳條件為:初始酒精度為6%、菌種添加量18%、裝瓶量50%,對以藷類等澱粉基原料進行醋的工業化生產具有一定指導意義。

Purple potato as raw material was used to produce purple potato vinegar by submerged fermentation after enzymol‐ysis .The results showed that :at 30℃ ,the optimal conditions of alcoholic fermentation was as:initial pH5 ,initial sugar 14% , yeast amount 0 .2 g/(100 ml);the optimal conditions of acetic fermentation was as :initial alcohol content 6% ,acetobacter addi‐tion amount 18% ,volume‐loading 50% .The results had a certain guiding significance for the industrialization of vinegar pro‐duction with potato starch material .
